To all whom it may concern:

Be it known that I, VILLIA'M N. STACEY, a citizen of the United Statesof America, residing at Springfield. in the county of llampden and Stateof Massachusetts, have invented new and useful Improvements in Devicesfor Binding and Holding a Sanitary Slab, such as Porcelain or the like,of which the following is a specification.

This invention relates to means and apparatus for binding and holding asanitaryslab. such as porcelain or the like, for a lunchroom chair arm,a table top, and other analogous uses.

The object of the invention is to provide improved means for holding andsupporting a slab of porcelain or similiar material in a rigid and safemanner, said means being so constructed that no crevices, cracks, orholes are present in the top surface of the assembled device into whichmoisture or foreign matter can enter to render the surface unsanitary.

Another object of the invention is to provide a clai'nping and holdingframe by which a slab of suitable material, such as porcelain, can berigidly held, and its edges protected without any holes being necessaryin. the slab. said frame forming together with the slab a perfectlysmooth unbroken top surface.

Another object of the invention is to provide a clamping frame for aslab of suitable material, such as porcelain, whereby the slab isclamped around its edge between two separate members of the frame, andthe frame is provided with a recess around and extending over the upperedge of the slab which recess may be filled with cement.

Other objects of the invention will appear in the detailed descriptionand more particularly in the annexed claim.

Referring to the drawings, Figure 1 is a top view of the frame memberassembled as it holds the porcelain slab; Fig. 2 is a bottom View of thesame; Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1; Fig. tis a detail sectional View taken on the line 4c--'l of Fig. 1; and Fig.5 is a de tail sectional view taken'on the line of Fig. 1.

Referring to Fig. 2, the frame, preferably made of metal, is shown in aform suitable lhe bottom frame member is lndicated by 1 and comprises asupporting ledge for the porcelain slab, as indicated in Figs. 3, l.

y and 5, and depending flanges S for con nection with the supporting armof the chair 111 any suitable manner. Suitable cross members, asindicated in Fig. 2. stiilen and brace the bottom frame member andprovide supports on which to convenientlv position the flanges The ledgeof this bottom frame provided around its entire edge with an upstandingflange and at intervals with upstanding lugs 5 for a purpose to bedescribed. The top frame memher is indicated at 2 in Figs. 1, El. -l-,and and comprises a closed band having a hookshaped upper extensionwhich overlaps the edge of the porcelain slab 3 and a depending flange10 extending entirely around the frame. In this upper frame member.there are provided depending lugs l which register with the upstandinglugs 5, and the two frame members 1 and 2 are bound together by means ofthe blind-screws 6 passing through the lugs l and 5. The upperhook-shaped port-ion of the upper frame member is best seen in Figs. land 5, and it will be noticed that a recess is provided hctween theframe members and the porcelain slab which recess surrounds the entireouter and upper edges of the porcelain slab.

\Vhcn the apparatus is assembled, the

porcelain slab is placed against the hookshaped member of the topfral-ne portion when this portion is upside down. Cement is then filledin all around the outer .edge of the slab so that it completelysurrounds this edge and the top edge as indicated at 7 in Fig. The lowerframe member is then placed against the bottom surface of the slab sothat the lugs t and lugs 5 register. The screws 6 may then draw the twoframe portions to bind the frame and slab together, and the cement whichis provided in excess quantity in the recess will be forced therein tofill the recess, surround the outer ed go of the slab member 3, andextend over the edge of that member. The apparatus is then turned rightside up, and, when whatever cement is squeezed out between the upperframe member and the top surface of the slab is scraped away and thecement is hardenei'l, the apparatus is ready for use.

The depending flange 10 and the upper hook-shaped portion ofthe framemember porcelain and analogous materials for handling foods, butconsiderable difliculty has been found in a suitably mounting suchmaterials in a proper manner. The device shown herein makes suchmaterials available in a novel and useful manner.

in the appended claim What I claim is A sanitary tray armfor a luncheonchair or the like, comprising, in combination, a lower closed loop framehaving means formed onits under side to support it from a chair or thelike and provided with a flat upper supporting surface, a slab ofporcelain or like Washable material ar-' ranged torest on said surfaceand be supported therefrom, an upper tray frame,

comprising, a closed loop arranged to fit over the Tower 'rame and theslab to conceal the formeand to form a smooth unbroken rounded rimaround and above said slab, said frame being of substantially hookshapedcross-section and formed with a short inner depending flange to rest onthe slab and a longer outer depending flange to form a skirt to concealthe lower frame and protect the user from corners and rough edges,.aseries of lugs formed on the interior of said tray frame and dependingtherefrom, securing devices arranged to pass through the lower frame andinto said lugs to draw the frames together to force the v slab intoengagement with the short inner My invention 1s more partlcularlydefined depending flange on the tray frame, all constructed and arrangedso that a recess is provided under the tray frame and around the topmarginal portions and the side edges of the slab, and cement or the likefilling said recess to form a closed water tight joint between the frameand the top surface of.

the slab.
